- Open bite: There is a dental malocclusion, and the edge occurs prematurely, with no contact between the upper and lower anterior teeth.
- Retrognathism or Class II: when the chin is drawn back, sometimes affecting speech
- Prognathism or Class III: when the mandible is advanced about the upper jaw
- Facial asymmetry: when there is an asymmetrical growth between the right and left sides of the face
